Magic World: Inferno

This turn-based strategy game offers a loot-driven progression system where players unlock units and upgrades through chests, but it suffers from significant pay-to-win mechanics and difficulty spikes that require substantial grinding or spending. Sessions can be medium-length, and while it's playable solo, the intense difficulty and monetization make it best suited for players who enjoy challenging progression and don't mind the potential for pay-to-win elements.
